' ApplicationFebruary 10, 1932.? s riarNa59ac35 a 16 claimszf(015197-39)"- 1 I am aware of the fact that page-endindica tors are notbroadly new, but I have found that they are'for the most partscumbersome, complicated and therefore expensive. 1 Furthermore;- all of the page-end indicators of which I-am aware are designed to constitute anintegral part ofthe typewriter, whereas the present'invention is intendedto be. an attachment which may .-be very readily and speedily secured toanyexisting type.- writer. 1 .In theiaccompan'ying specification I shallidescribe, and in the annexed drawing show,..an. illustrative embodiment of thepage-end'indi'cators of the present invention. It,is,however, to be clearly understood thatI do notlwish to be limited .to the exact construction herein shown In the accompanying drawing: Fig; 1 is a side elevational viewbf-the aforesaid illustrative embodiment of thepresent invention, the same being partly in section .tofshow the internal construction; and Fig. 2 is a front elevational view of the same: Referring nowmore' in detail to theaforesaid illustrative embodiment-of the page-end indicators of the present invention, and with particular reference to the drawing illustrating the same, the numeral 10 generallydesignates the carriage .of a conventional typewriter, which carriagelcarries the platen-or roller 11 with which cooperates the paper guide112, therplatenand paper'guide being adapted to" accommodate between the. same a'sheet' ofpaper P. .1

, Secured to'any desired part of the carriage :10,

. to the rear of the platen 11, by means of screws 13, isa triangular plate 14410 which in' turn is fixed, by meansof screws 15, -a vertical support The bar 16 is provided, on thefront face thereof, with rack teeth 17, and adapted to slide vertically'over the bar 16 isa tubular. guide 18,

of square cross section, to fitthei banfformed ona rectang'ular'casing 19; Theilowerwallof and described for purposes of illustrationaonly;

the casing 19' is provided with a downwardly vdirected lug 20v in which thereis rotatably mounted apintle21 having fixed at the inner end thereof .a-pawl -22 adapted to cooperate with the teeth 17:.o-f the bar16. The pawl 22 is normally maintained in engagement with the teeth 17 by means of a flat spring'23. one end of which is' fixed. to the pawl and the other'end of which urges against the under. surface of the lower wall of the 'casing 19; In order to disengage the pawl 22 from the teeth. 1'7 .oftthe bar 16, Iprovide 1 the outer end of .the'ipintle 21 with'an operating member 24.

Thus, the casing'may be moved freely upwardly but cannot be moved downwardlyunless the pawl 22 is first disengaged from the teeth '17 by means of the operating member 24. The purpose of this arrangement will become-apparent as, the descriptionprogresses. Fixedto the top. wall of thecasing; within the same. is apair of. U-shaped supporting brackets 25 and '26. the lower ends of the arms of said brackets being adapted to r'otatably support a. shaft 27; Fixed upon the shaft 27intermediate the arms of the inner bracket 25..is a solid'dru'm 28 about which is. coiled a spring 29. the inner end.3(lxof'thezspring'bein fixed to the drum 28 and the outer1end 31 or such spring being 'fixe at-.32 w the reariwallof'the casin '19.

....Fixe'd upon theishaft 27;intermediate thearms of 'the'innerfiand outer brackets 25 and 26 is a apair of reels: 33, each .of which isadapted to carry a coil of wire 34/ of a'certain definite length,

as will'hereinafterbemore fully. explained. The coils of .wire34 constitute supports which pass ----downwardly out of the casing 19 through guides 35, the lower ends 36 of such'wire supports being "looped'toTsupporta clip generally designated by reference character 37. The clip-37 consists of the grippingtjaw's38 normally urgedtogether by means of asp'ring-39, the jaws extending upwardly beyondthe springto formoperating'handles 40.

The wire supports 34 are connected adjacent the top of the clip 37 by across bar 41.

The length of the wires 34.- is such that when almost all of the sheet of paper P'has passed almost entirely about the platen 11; in other words, when the end of the pageisabout to be reached by the operator. Thus, by regulating the height of theicasing' '19 on the bar 16,"the clip 37 can be made to disengage'from the paper P -when' the paper has passed predetermined distancesthrough the-machine. 'By this means, the

typist can in advance, knowing how much written matter he desires on any particular sheet of paper, cause a signal to be given when the paper has passed a predetermined distance through the machine. The signal which I prefer to employ is as follows:

Fixed to the undersurface of the lower wall of the casing 19, adjacent the front edge thereof, is a bracket 42 which is adapted to pivotally carry a tripping lever 43, the inner end- 44 of which is positioned in thepath of the cross bar 41 and the outer end of which carries a clapper 46 adapted to cooperate with a bell 47 carriedat as by the front wall of the casing 19.

This completes the description of the aforesaid illustrative embodiment of the'page-end indicators of the present invention. It will be noted from such description that the same are simple in construction, easy and economical to fabricate and assemble, and admirably adapted to perform the intended functions.

It is believed that the operation of the aforesaid illustrative embodiment'of the present invention is clearly apparent from the foregoing description, but forv purposes of clarity the same may be briefly summarized as follows: A

After the typist has inserted the sheet of paper P in the machine in the .usual manner, he approximates'how much space on the sheet of paper will be necessary to-include all of the matterto be written, and by employing ascale 49 which may be carried by the bar 16, slides the casing 19 over the bar 16 until the pawl 22 is engaged with the tooth 17 corresponding to the space that he has determined will be necessary. The

clip 3'? is then engaged with what will be the lower edge of the sheet P,.this being done by pressing together the operating handles 40 and inserting the sheet P intermediate the gripping jaws-38 and there'afterreleasing the handles 40.

The typewriter is now operated in the usual mannerand as soon as the paper 'has passed through the machine. the distance to which the device has been set, the wire supports 34 will become taut, having been unrolled their entire length, thus preventing the clip 37 from further following the sheet P. Obviously, during the unrolling of the wiresupports 34, the shaft 27'has been rotated so as to wind up the spring 29. Any continued ,movement of the paper P through the machine "causes the clip 3'7 to become disengaged from the paper and the spring 29 will be free to rotate the shaft 2'7 in a direction opposite to that'in which it was rotated during the winding up of the spring. This will cause the clip to move upwardly toward the casing and the cross bar 41 to come in contact with the inner end 44 of the tripping lever 43. The latter will be pivoted in the bracket 42 to causethe clapper 46 3 to ring'the bell 47, thus giving the operator, an audible signalthat the paper has passed through the machine the predetermined distance to which the device had'been set.

Obviously, if the operator determines that. the

amount of written matter which he is desirous of typewriting will cover more than one sheet of paper, the device is set so as to permit the paper to pass almost its full length through the ma chine before the clip 37 willbecome disengaged from the paper.-

This completesthe description of the mode of use and operation of the page-end indicating devices of the present invention. 7

As before stated, it is believed that this invention includes a page-end indicator which is exoeedingly simple in construction, very easy and economical to fabricate and assemble, and adapted to perform its intended functions in a very efficient manner.

Other superiorities and advantages of the means of the present invention will readily occur to those skilled in the art to which the present invention relates.
